Aventon launches Aventure M, a mid-drive fat tire e-bike with auto-shifting

Aventon is giving its popular fat tire e-bike a serious upgrade. The company just unveiled the Aventure M, a new mid-drive version of its best-selling Aventure model. With more torque, smarter shifting, and a boost in connectivity and control, Aventon says this is the “most advanced” bike it has ever produced.

The new Aventure M swaps out the rear hub motor for a 100 Nm mid-drive motor, offering more efficient power delivery and a more natural ride feel thanks to its double-sided torque sensor. And in case that 100 Nm doesn’t exactly place it for you, just know that we’re talking about more power (or more accurately, torque) than nearly any other e-bike in this class.

The Aventon A100 motor, which is rated at 750W and runs on a 36V system, takes full advantage of its Class 3 category with pedal assist speeds up to 28 mph (45 km/h) and a throttle top speed of 20 mph (32 km/h). The throttle is sold separately, probably as a nod to being even more compliant with California’s new stricter laws regarding Class 1 and Class 3 e-bikes, which can’t have mounted throttles.

Aventon also gives riders the option to set the bike to Class 1 or 2 limits using the companion app. We’ve always been pretty impressed with Aventon’s app, as it’s quite easy to use and makes it simple to control those types of modifications to the bike.

That app pairs with Aventon’s newly developed ACU (Aventon Control Unit), a custom IoT system that adds a wide range of smart features. Riders get GPS tracking, theft detection, geofencing, remote locking, and over-the-air (OTA) firmware updates. Aventon even built in a passcode-locked on-switch for added security, as well as a physical rear-wheel lock and alarm.

We’ve previously seen Aventon use that OTA update system to give its e-bike more power via a boost feature, so the company doesn’t appear shy about pushing out new features when they’re ready.

But it’s not just about motor placement and connectivity. The Aventure M introduces electronic shifting, powered by a 10-speed Shimano CUES drivetrain and paddle shifters. Riders can shift manually or let the system take over with Auto Shift, Aventon’s torque and cadence-sensing automatic shifting mode. A new Uphill Start Assist feature gives riders an extra torque boost when starting from a stop on steep grades –perfect for off-road adventures or fully loaded cargo rides.

As for range, Aventon claims up to 85 miles (137 km) from the removable 36V 20Ah (720 Wh) battery, which itself weighs around 8.7 lbs (3.9 kg). That figure is in the lowest power level, and real-world range will depend heavily on terrain and assist level, but riders can likely expect something in the 40–60 mile (65-100 km) ballpark under typical pedaling usage when enjoying moderately higher power levels, and a bit less if leaning hard into that optional throttle.

Rounding out the build are 4-inch wide fat tires, a suspension seatpost, and an 80 mm front suspension fork. The total weight of the bike is around 73 lbs (33 kg), which is actually surprisingly reasonable for a full-featured fat tire e-bike with a mid-drive, believe it or not. Hey, these are heavy bikes when you stuff all that power, range, and tech in there.

The price at launch is US $2,899, which places the Aventure M above the hub motor version of the company’s existing Aventure model but below some other mid-drive fat tire options on the market. Aventon is clearly positioning this as a higher-performance alternative that’s still (hopefully) accessible to the average rider. It’s available now online and through Aventon’s network of over 1,800 partner dealers across the U.S.

Electrek’s Take

It’s about time we saw a major direct-to-consumer brand bring a smart tech, mid-drive fat tire e-bike to market that doesn’t require taking out a second mortgage. The Aventure M feels like a natural progression for Aventon – taking what made the Aventure 2 so popular and layering on meaningful performance and tech upgrades. The mid-drive motor brings real climbing power and smoother pedal assist, and features like auto shifting and built-in GPS tracking give this bike some serious smart credentials.

Of course, at nearly $3,000, this isn’t exactly budget territory anymore. But considering the Aventure M includes high-end components, a full-fat-tire adventure build, and an impressive level of integration, it still looks like a solid value for someone who wants their e-bike to go above and beyond the basic level of componentry and features. If the real-world range holds up and the automatic shifting works smoothly, this could easily become a category leader for anyone wanting an all-terrain e-bike that feels as refined as it is rugged. Aventon of course didn’t reinvent the wheel here — they just made a smarter, better one. I look forward to getting on one soon for a review and letting you know what I think of the ride.
